Rather than viewing the Graeco-Roman world as the “background” against which early Christian texts should be read, Abraham J. Malherbe saw the ancient Mediterranean world as a rich ecology of diverse intellectual traditions that interacted within specific social contexts. These essays, spanning over fifty years, illustrate Malherbe’s appreciation of the complexities of this ecology and what is required to explore philological and conceptual connections between early Christian writers, especially Paul and Athenagoras, and their literary counterparts who participated in the religious and philosophical discourse of the wider culture. Malherbe’s essays laid the groundwork for his magisterial commentary on the Thessalonian correspondence and launched the contemporary study of Hellenistic moral philosophy and early Christianity.
